ALBERT PEPPIN, OF DIORITE, MICHIGAN.

PIPE-RAISING DEVICE.

Specification of Letters Patent.

Application filed March 31, 1911.

Patented Sept. 19, 1911.

Serial No. 618,114.

To all whom it may concern:

Be it known that I, ALBERT PEPPIN, a citizen of the United States,residing at Diorite, in the county of Marquette and State of Michigan,have invented certain new and useful Improvements in Pipe-RaisingDevices, of which the following is a specification, reference being hadto the accompanying drawings.

My invention relates to new and useful improvements in pipe raisingdevices and more particularly to a device for raising a pipe so that thesame may be readily cou pled to another pipe and my object is to providea device of this character which will grip a pipe so that the same maybe raised and coupled to another pipe while in raised position.

A further object of the invention resides in providing a portion of thedevice rotatable which directly grips the pipe, and a still furtherobject is to provide a ball bearing rotatable portion.

A still further object resides in providing removable Wedges adapted tobe used in connection with the rotatable member to grip the pipetherein.

A still further object is to provide a device of simple construction andone which is extremely effective in operation.

With these and other objects in view, my invention consists in the novelfeatures of construction, combination and arrangement of parts as willbe hereinafter referred to and more particularly pointed out in thespecification and claims.

In the accompanying drawings forming a part of this application, Figure1 is a side elevation showing my improved device applied to use. Fig. 2is a top plan view of the device. Fig. 3 is a longitudinal sectionthereof as seen on line 33, Fig. 2. Fig. 1 is a detail perspective ofthe rotatable member. Fig. 5 is a similar view of one of the ringmembers. Fig. 6 is a detail perspec tive of one of the gripping wedges.

In carrying out my invention, I shall refer to the drawings in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which 1 indicates a rafter or timber of anydesired type extending horizontally of the ground and mounted aconsiderable distance thereabove, through which extends vertically apipe 2. This rafter or timber 1 may be in use in any connection, butparticularly in mines, wherein an additional pipe 3 is adapted to beraised and coupled by means of the coupling 1 to the lower end of thepipe 2 which extends through said timber.

In order to provide for the raising of the pipe 3, I have provided myimproved gripping or raising device, comprising an elongated frame orbase member 5 increasing in width toward the center thereof and havingextending therethrough an enlarged central opening 6, said opening beingreduced adjacent the bottom face of said frame to form an annularshoulder 7 therein. The shoulder 7 is grooved to receive the bearingballs 8 and mounted within the enlarged opening 6, is a circular centralblock 9 also having an annular shoulder 10 thereon adapted to rest onthe bearing balls 8 carried on the shoulder 7 and thus, said block 9 iscapable of being readily rotated within said frame 5. In order to retainsaid block 9 within the frame 5, however, I pro vide the upper and lowerring members 11 and 12, respectively, the outer edges of which extendover the edges of the opening 6 in said frame, and which are secured tothe block 9 by extending the bolts 13 therethrough and securing the sameby means of the nuts 14. The block 9 is provided with a central opening15 equal in diameter to the openings in the rings 11 and 12, and thewall of said opening 15 is provided at diametrically opposite pointsthereon with the recesses or grooves 16, the rear wall 17 of saidrecesses or grooves being inclined downwardly from the upper to thelower ends, the purpose of which will be hereinafter and moreparticularly described.

The inner peripheries or walls of the openings in said rings 11 and 12are like wise provided with recesses or grooves 18 in registration withor at points coinciding with the grooves 16 in said block 9, and therear walls of said recesses 18of the rings are also inclined inwardlyfrom their upper to their lower ends, coincident to the inclination ofthe rear walls of the grooves 16. In View of the fact that the rings 11and 12 are mounted on opposite faces of the frame 5, it will be seenthat the grooves 18 therein have the walls thereof inclining in oppositedirections when considering the two ring members together, and adaptedto be inserted within the alining grooves 16 and 18 of the block 9 andin the ring members,

are a pair of wedges 19 and 20 which are adapted to be retained to thering 11 by means of the chains or the like 21'. These wedges l9 and 20have their effective faces ,concaved and provided with corrugations 22,whereby a circular object such as a pipe may be inserted through theopenings in the block 9 and rings 11 and 12 and be securely gripped forraising purposes. I have also provided the ends of the frame member 5with threaded sockets 23- adapted to receive the threaded ends ofthehandle members 24, whereby the device may be readily carried and appliedto use, and in order to raise a pipe member after the same has beengripped by this device so that said pipe may be coupled to the lower endof an additional pipe over head, said frame member isv provided adjacentits ends with the eye bolts 25 which are linked to the pulley blocks 26.Additional pulley blocks 27 are suspended from the rafter or timber 1and extending over the pulleys in said blocks 26 and 27 are the cables28, and it will be seen that when the ends of said cables are drawn, theframe 5 with its adjunctive parts extend vertically, wherein the lowerend of one pipe extends through a rafter or timber a considerable heightabove the ground. l/Vhen it is desired to couple an additional pipe tothe lower end of the pipe overhead,

the frame member is slipped over the lower end of the additional pipe sothat the wedges.

within the central block securely grip the same. By drawing upon theends of the cables 28, as described, the additional pipecarried by theframe member will be raised so that the upper end thereof will be in:position to be coupled with the lower end of;

the pipe above. The end of the cables may then be secured in any desiredmanner so:

as to retain the frame and pipe in such a, position, and as the couplingwill have been; secured to the upper end of this additional pipeprevious to the raising thereof, it will be seen that said additionalpipe may be rotated within the frame to screw the coupling thereof ontothe lower end of the other pipe.v hen the pipes have been properlycoupled, the wedges may be removed from their effective positions sothat the frame and its parts may be readily removed from the pipe towhich it is secured.

Such a device as I have invented, it will be seen, is particularlyadapted for use in mines wherein it is often desired to couple pipesextending vertically, as shown in the drawings and described in thespecification, and it will be seen that by having the central portionwithin the frame which is rotatable therein, the pipe is capable ofbeing rotated so as to be readily coupled to an additional pipe above.In view of the rotating, gripping portion of the invention, it will beappreciated that a simple screw coupling is the most effective whenusing a de vice such as this, so that by merely rotating the pipecarried by the frame member when the same has been properly positioned,it may be readily coupled to the other with no difficulty whatsoever.

It will further be seen that by providing the bearing members betweenthe central block and the frame in which it rotates, said block may berotated with little or no friction, and it will still further be seenthat the device is of such simple construction as to be veryinexpensively manufactured and one which is extremely effective inoperation.
